Fill it yourself.
To use the O.penVape you need a battery as well as the cartridge.
Pre-filled cartridges are also available.
The O.penVape vaporiser is handy, versatile and discreet. It is about the size of a pen.
To use, a cartridge is screwed onto the battery, then inhaled through the mouthpiece. The pen works with a vacuum sensor with no need to press any buttons. As long as the light is on at the lower end of the battery, then you can inhale. (Up to 8 seconds)
The CBD product should not be used during pregnancy or when breastfeeding. It is to be used as a dietary supplement. For those over 18 years of age.
